Our entry for Ludum Dare 31. Game made in 72 hours (or less - we did sleep some!). Multiplayer game for up to X* players. Feature: you can easily create and add your own maps!
*We have only been able to test with 10 players, so far, but we think this game could be played with at least 16 players. Probably up to 64. If you try with more then 10 players, please let us know how it went (gridcars [at] gmail.com)!
